wiring,.. help please

so i took the stock tape player out of my 90 probe gt and on my new cd player it says what all the wires are by color, but the tape player wire colors are different than the cd player's and i dont wanna figure out what every single wire goes to, so i thought i'd ask here if anyone knew what the wires are by color from the stock system of a 90 probe gt.
thanks!

just look at what the speaker wire are by looking then figure whuch is left. Red=positive Black=Ground.
i'm not sure off by hand, but performanceprobe.com should have it.
